The essential function of DC DC converters is to change the voltage of direct current.They have many applications both in day-to-day use home appliances and hi-tech machines.A step down Dc Dc Converter lowers voltage, whilst a step up system adds to the voltage.
An inductor, an inverter and a transformer are the three basic parts of a Dc Dc converter.At times other parts are also present in these units based on their specific application.
Dc to Dc converters have several applications in our daily life.The most popular example is a cell phone.When the power stored in a cell phone goes down after some time, the voltage also lowers.With a decreased voltage, the mobile phone cannot work and therefore these systems are used in mobile phones to bring the voltage to the required levels.Sometimes the circuits on electronic devices have certain voltage requirements, which may be not the same as the voltage that comes from the power source and thus these converters are used in those appliances.
Non-isolated and isolated are the two different kinds of Dc to Dc converters.Basically an isolated Dc to Dc converter works like a barrier between the input and output. Other common components of an isolated Dc Dc converter are sub circuits and a voltage stabilizer. The sub circuits have distinct voltage specifications, a few being greater and some being lower than the voltage supply; a few can even be negative. The converters have several medical applications because they can provide positive as well as negative output. There are further two types of isolated converters - forward and flyback, which are differentiated by their functioning.
More Dc To Dc Converters Info: Rather than an inductor, a transformer stores the energy in a flyback isolated converter. They are usually used in lower power equipment, which pull less current such as cathode ray tubes. The transformer acts primarily in transferring the energy in one step in the forward isolated converter. This kind of Dc to Dc converter can increase as well as reduce the voltage or give a combination of the two. The car amplifiers utilize these kinds of converters to step up the voltage to get a higher output.
The second kind of Dc to Dc converters, which are non-isolated converters are utilized for increasing or decreasing voltage by a minimal ratio. Buck, boost, buck-boost, cuk and charge pump are the five different types of non-isolated converters, each one of these having different uses and functions.
You must select a reputable distributor to buy DC DC converters, if you require these components. Some suppliers even offer modification based on your requirements. You can get custom made characteristics like higher temperature ranges and multiple switching frequencies if you believe that your requirements are unique and a general model won't work well for you. Travelers can also utilize these converters to use their home appliances in any country since the voltage provisions are distinct in different parts of the world.
